The SMP1352-040LF is a plastic packaged, surface mountable PIN diode designed for high volume switch applications from 10 MHz to beyond 2 GHz. The low capacitance of this diode (0.25 pF) combined with its low resistance (1.0 Ω typical at 100 mA) make the SMP1352-040LF particularly well suited for high-isolation, series-connected PIN diode switches in batteryoperated circuits. The SMP1352-040LF is also available in a variety of plastic packages including an SOD-23 (SMP1352-011LF) and the small footprint SC-79. Design information for high power switches may be found in the Skyworks Application Note, Design With PIN Diodes (document number 200312) .
